GASKET.

I Application filed December 31, 1921. Serial No. 526,163.

My invention relates to a gasket and has in contemplation, particularly, an improved form of gasket forsoaling the joint between the supply or exhaust manifold of an internal combustion engine and the cylinder block of the engine, or between similar ported engine or machine parts requiring a sealed joint. i I

The type of gasket'which this invention is designed particularly to improve upon is made principally of sheet metal, such as copper, and comprises an annular, hollow or channeled body that is intended to lie between the engine parts to be connected, for example, between the manifold and the cylinder blockyand which contains, preferably, a body-of asbestos, or like compressible material, such annular body being formed with oppositely'extending flanges that project into the manifold and cylinder block ports, respecti'vely.- V The principal object of this inventionisto improve upon gaskets of this general. type by providing certain novel constructions whereby the effectiveness of the gasket as a seal .is bettered; whereby the gasket as awhole, butwith respect particularly to the projecting flanges thereof, is strengthened and rigidifledas against the danger of being crushed and bent in handling and such ri-;

gidification accomplished without seams, recesses or parts likely to be expanded or dis torted by the gases passing through the gasket; and whereby the gasket 1s adapted to take a grip orhold upon one of the parts, for example, the manifold, into which it is inserted so as to facilitate the attachment of this part to the other engine or machine part with which it is assembled.

The invention is illustrated, in a preferred embodiment, in the accompanying drawing, wherein- Fig. 1 is a cross sectional view of the gasket on. a magnified scale.

Fig. 2 is a View, in perspective, of the gasket, and j g V Fig. 8 is a sectional view of portions of an internal combustion engine, manifold and cylinder block showing the gasket in place between these engine parts.

Referring to the drawing, the gasket consists, in its preferred embodiment, of a channeled, annular structure provided with lateral flanges and of an integral or seamless ring member arranged within said chancomposed preferably of: two parts or members,-a member 10, formed with an outstatld neledstructure. The channeled structure ing flange 14 which extends within the chan-.-

neied portion 12 oft-he other mem'ber, and a lateral flange 15 The ring rirreinforcing member 16 is arranged within members 10 and 13 and extendsacross the channel 17 and across both of the flanges 11 and 15.

Preferably the edges 18 and 19 of the ring 11 are bent over the edges of flanges 11 and 15, respectively. 'These bent over edgesmay be pressed down flat upon the flanges,,as is the case with the bent over edge .18, but

preferably one edge, at least, is not pressed down upon the sub-jacent flange but is allowed to stand at aslightly oblique-angle thereto,as indicated with some exaggeration, in the case of the bent over'edge'19.,

The channel 17 j is preferably. filled with some j compressible material not liable to deterioration when heated. Preferably this filler is composed of a body of asbestos 20.

X In Fig. 3, 21 indicates a portion ofthe supply or exhaust manifold of an internal combustion engine and'22 the cylinder block. The gasket is arranged between these. engine parts so thatthe channel portion-thereis clamped or otherwisefastened to the cylinder block.

In assembling the manifold it is customary to first put the gasket into the manifold port and then attach the manifold to the cylinder block, inserting. the outstanding flange of the gasket into the cylinder block port. By having the outer edge of the gasket flange which goes into the manifold port of three ply construction, and particularly by having the overlapped edge of the ring 11 upstand- :ofisftightly conipressed when the manifold ing a trifle from the body of the flange, as

indicated at 19 (Fig. 1), the gasket will fit the manifold tightly enough so that it is being assembled. The two ply construction of the lateral flanges of the gasket, and the beaded or three ply construction at their edges, give very considerable strength and rigidity to the flanges so that they are not easily crushed, bent or distorted. As the gasket fits rather tightly into the cylinder block the flange on this side of the gasket is likely to be bent or crushed when the .not likely to fall out when the manifold is I llO manifold is assembled with the cylinder block, unless the edge of the flange is strongly reinforced. The ring 11 extends across the channel containing the asbestos tiller, and across both lateral flanges so that the interior of the gasket presents a smooth, unbroken, seamless surt'ace which insures a per- 'tect seal of the joint between the engine parts.

\Vhile I have described my invention in a preferred embodiment, it will be understood that structural modifications may be made without departing from the principle of the invention as deflned'in the appended claims.

I claim:

1. In a gasket, the combination with an annular structure having a circumferential recess tor a filling material and formed with laterally projecting flanges of equal diameter, of an interiorly arranged ring member extending across said recess and both flanges and in engagement with both flanges over its axial length, and beaded over the edges of the flanges.

2. In a gasket, the combination with an annular structure having a circumferential recess for a filling material and'iormed with laterally projecting cylindrical flanges of equal diameter, of an interiorly arranged ring member extending across said recess and one of said flanges in engagement therewith over the entire height of said flange and bent around so as to overlap the edgeof said flange and means for securing said ring member to the other flange.

3. In a gasket, the combination with an annular structure having a eircun'iferential recess for a filling material and formed with laterally projecting flanges, of an interiorly arranged ring member extending across said recess and one of said flanges with its edge bent over the edge of said flange to stand at a slightly oblique angle thereto, for the purpose described.

4-. In a gasket, the combination with an annular circumterentially channeled structure having outstanding flanges of equal diameter, of an interiorly arranged ring nenr ber extending across said channel and one of said flanges and in engagement therewith Over the entire height of said flange, with its edge bent over the edge of said flange, the bend portion oi the ring being in en gagement with the edge of said outeistanding flange.

5. In a gasket, the combination of three annular metal members, one formed with a channeled portion and a lateral flange, another with an outstanding flange extending into said channeled portion and with a lateral. flange, and the third arranged within the other two and having edges which overlap, respectively, the edges of said flanges.

6. In a gasket, the combination with an annular structure having a circumferential recess and formed with laterally projecting flanges, of a seamless reinforcing member arranged within said annular structure with its edges overlapping the edges of said flanges.

7. In agasket, the combination with an annular structure having a circumferential recess and formed with laterally projecting flanges of equal diameter, of a seamless reinforcing member arranged within said annular structure and engaging said laterally projecting flanges each on opposite sides of the same.
